India's first bullet train project is rapidly taking shape across the varied landscapes of Maharashtra's Thane and Palghar districts, with major civil construction and tunnelling works advancing on the Mumbai-Ahmedabad High-Speed Rail corridor.
The project is being developed under the Centre's broader push to modernise India's railway infrastructure and introduce next-generation high-speed rail technology.
Union Railway Minister Ashwini Vaishnaw shared glimpses of the ongoing construction, showcasing the scale of infrastructure development along the 135.45-km elevated stretch between Shilphata in Thane and Zaroli village on the Maharashtra-Gujarat border.

Pier construction has progressed across more than 100 km, while around 74 km of piers are ready for viaduct girder installation.
Nine casting yards, seven full-span launching gantries and eight segmental launching gantries are currently operational in Maharashtra.
